ALBIN XVAR'IH, OF STAPLETON, NEW YORK.

CLOTH-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 391,285, dated October 16, 1888.

(No model.)

To all whom it may concern:

Be it known that I, ALBIN WARTII, a citizen of the United States, residing at Stapleton, in the county of Richmond and State of New York, have invented new and useful Improvements in Cloth-Cutting Machines, of which the following is a specification.

Thisinvention relates to certain novel means for imparting motion to the cutting mechanism, as fully explained in the following specification and claims, and illustrated in the ac companying drawings, in which- Figure 1 represents a side elevation of my cutting-machine. Fig. 2 is a transverse section in the plane a: m, Fig. 1, on a larger scale than the previous figure. Fig. 3 is a plan of a portion of the same on the same scale as Fig. 2. Fig. 4 is a side elevation of a modification. Fig. 5 is a plan or top view of the same. Fig. 6 is a detached vertical section of the cutting mechanism shown in Figs. 1, 4, and 5 on a larger scale. Fi 7 is a side elevation, partly in section, showing a different cutting mechanism.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a table, which is intended to support the material to be cut. On one side of this table and above its top is secured a rail, B, the ends of which are supported by anysuitable means such as standards (3 C, Fig. 1. On the rail B is placed the carriage D, which is provided with two wheels, a a, which are grooved so as to fit the rail 13, and in order to retain the carriage on the rail in an upright position I secure to its under side an arm, I), which carries two wheels, 0 c, and these wheels are brought to act upon the opposite sides of a fiat rail, (7, which is secured to the table A beneath its top. (Best seen in Fig. 2.) By these means the carriage is free to move from one end of the table to the other, it is always kept in an upright position, and it leaves the entire surface of the table practically free for the adj ustment of the work.

On the carriage D is placed the electromotor E, which may be of any well-known constructionsuch, for instance, as that known as Edisons electromotor --and which connects with a battery or other source of electricity by wires 10 and 11. These wires may be made to connect directly with the source of electricity,

as indicated in Fig. 4, and in that case they must be madelong enough and brought in such a position that they do not interfere with the movement of the carriage D upon the rail B; or said wires 10 and 11 may be made to extend from the binding-posts of the electromotor to bellcrank levers E E, Fig. 1, which are mounted on standards E E, rising from the frame of the electromotor, and which carry metallic rollers E E". These rollers are held in contact with wires 12 13 by the action of springs E E Said wires are supported by standards which rise from the table A, and they connect by wires 14 15 with the source of electricity.

The base plate F of the frame of the electromotor can be firmly secured to the carriage, Fig. 7, or the connection can be made by means of a pivot, 6, so that the electromotor can be free] y swiveled round in either direction, Figs. 1, 3, 4, and 5, and for the purpose of locking the baseplate a pin, f, is used, which can be inserted into a hole in the base-plate and into a corresponding hole formed in a lug, g, which projects from the carriage D. (See Figs. 1 and 4.)

On the base-plate F is secured a standard, H, which forms the bearings for a pivot, f, in which swings the arm K. The standard H may be rigidly secured to the base-plate; but I prefer to make the connection between the standard and the baseplate by means of a pivot, g, on which said standard can freely swivel in either direction; and for the purpose of locking the standard in position I use a pin, it, which is passed through a hole in the lug lz ,which proj cats from the standard and through a corresponding hole in the base-plate.

On the free end of the arm K is firmly secured a bracket, L, which carries the cutting mechanism. In the example shown in Figs. 1, 4, 5, and 6 of the drawings this cutting mechanism consists of a cloth-lifting foot-piece, M, from which rises a pillar or standard, N, which extends through eyes i t on the bracket L,and on which is secured a handle, 0, by means of which it, together with the foot-piece, can be turned in either direction. Into the interior of the pillar N is fitted the cutter-bar P,which carries the cutter P, Fig. 6, and which engages a sleeve, Q, which fits the pillar N. In the arm K is mounted a crank-shaft, j, which carries a pulley,k,and from the crank of which extends a pitman, l, to one arm of a doublearmed lever, m, the other arm of which engages the sleeve Q on the pillar N. The weight of the sleeve, the cutter-bar, and the cutter is balanced by a weight, a, secured to the doublearmed lever m. The arm K is made in two sections, which are held together by a set proper tension of the belt can be maintained.

If the belt 7' extends directly from the pulley g to the pulley k, the standard H must be locked in position and the base-plate F must be unlocked, so that it can freely swivel on the pivot 6. Instead of extending the belt 1' from the pulley q to the pulley k, as shown in Fig. 1, intermediate pulleys, s t, can be provided, as shown in Figs. 4 and 5. These pulleys are firmly connected, and they are loosely mounted on a vertical arbor, c, which is firmly secured in the base-plate F of the electromotor, and on which the standard H is made to swivel. The pulley 11 connects by a belt, 1", with the pulleys, and the'pulley It connects by a belt, 1*, with the pulley It. If this belt-conneetion is used, the base-plate F can be locked and the standard H can be released, so as to be free to swivel round the arbor c.

When the electromotor E is started, the required motion is transmitted to the cutter P either by means of the belt r, crank-shaftj, pitman Z, lever m, and sleeve 0, as shown in Fig. 1, or by the belts r r, as shown in'Figs. 4 and 5, and the cutting mechanism can be moved over the table A in any desired direction without disturbing its connection with the electromotor, the latter being placed upon the carriage D, so that it partakes of some of the movements of the cutting mechanism, and it is always maintained in the proper relation to the same.

In the example shown in Figs. 1 to 5, inclusive, the electromotor E is placed upon the carriage D, so that the shaft 1; occupies a horizontal position, and the cutting mechanism shown in these figures has a reciprocating eutter, while the swinging arm K swivels to a part of the electromotor-frame, which part is the base-plate F of the frame. In the example shown in Fig. 7 the electromotor E is secured upon the carriage D in such a position that its shaft 10' occupies a vertical position.

and the cutter P shown in this figure is a rewhich is carried by the bracket L, formed on or firmly secured to the arm K. This arm swivels to a part of the electromotor-frame, consisting of a portion which extends around the shaft p of theelectromotor, and the bracket L forms the bearing for a shaft, 10*, which is geared together with the cutter-shaft p and which carries the pulley k, that connects by the belt 0' with the pulley q of the electromotor.-

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a table, A, a traveling guided carriage, D, an electromotor, E, having a base-plate, F, located above, secured to and traveling with the carriage, a swinging swiveled arm, K, having a cutter mechanism mounted on and moving with the arm and con nected with the electromotor to operate the cutter, and electrical connections for the electromotor, substantially as described.

2. The combination, with the table A, of the carriage D, the swivel-plate F, secured to the carriage, the electromotor secured to the swivel-plate, suitable connections between the electromotor and a source of electricity, the arm K, connected to the swivel-plate, the cloth-lifting foot-piece M, the cutter P, carried by the foot-piece, the bracket L, carried by the arm K and connected to the foot-piece, and means, substantially as described, for transmitting motion from the electromotor to the cutter P.

3. The combination, with the table A, of the carriage D, the swivel-plate F, secured to the carriage, the electromotor secured to the swivel-plate, suitable connections between the electromotor and a source of electricity, the arm K, connected to the swivel-plate by a pivot, f, the cloth-lifting foot-piece M, the cut I ter P, carried by the foot-piece, the bracket L, carried by the arm K and connected to the foot-piece, and means, substantially as described, for transmitting motion from the electromotor to the cutter P.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses. I
